Here's the deal, I had my 327 SJ block prepped and bored 0.040 over. Everything is good on the block. The problem is the crankshaft.

It showed cracks after magnafluxing.

I already bought the 0.040 over pistons and they are fitted on the rods.

Anyone have a good SJ crank for sale? What other options might I have to get around this problem?
